This invention relates to a quick detachable wheel mounting unit for boats.

It is an object of the present invention to provide a detachable wheel for a boat which can be easily and quickly detached from the boat after the boat has been put afloat or can be attached while the boat is still afloat and before the same is dragged onto the beach and whereby to lighten the load of persons using a boat.

Other objects of the present invention are to provide a wheel mounting unit for a boat which is quickly detachable simple in construction, inexpensive to manufacture, convenient to use and eflicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a side elevational view of a boat and of a quick detachable wheel mounting unit connected thereto.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 2.

Fig. 4 and Fig. 5 are sectional views taken generally on line 55 of Fig. 2 and showing respectively the positions of the wheel mounting upon being extended into the receiving member on the boat and after the mounting has been turned to retain the same against vertical displacement.

Fig. 6 is a longitudinal sectional view taken on line 66 of Fig. 3.

Referring now to the figures, l represents a boat having a side l2 upon which a mounting bracket 13 is secured. This mounting bracket has a slot l4 accessible from the top of the same and through which a flange l of a wheel axle l6 may be extended. The mounting bracket I3 is secured to the side of the boat l2 by bolts l1 extending through the side of the boat and by a clamping. plate l8 on the inner face of the boat. Nuts extend over the bolts as indicated at [9. An

axle extension 2| has a wheel 22 journalled on the same. A nut 24 holds the wheel in place on the extension 2|. The axle has a pin 25 adapted to engage with horizontal seat or cut out 26 within the recess l4 whereby the axle will be stopped from rotation by arm 21 with handle 28 thereon. The flange I5 has straight sides 30 so that it can enter the slot l4. Thereafter the axle is turned so that the flange extends horizontally as shown in Fig. 5 so as to be held against vertical displacement through the upper end of the slot H.

The bracket l3 includes laterally spaced apart 2 Claims. (01. 80-$15 1 walls I and 2 which enclose the recess M. It will be seen from the drawings that the recess I4 is open at the top and circular in configuration therebelow. The wall 2 includes a vertical slot 3 that terminates in a cutout 4 and the width of the slot is less than the width'of .the corresponding portion of the recess l4, while the size'ofthe cut: out 4 is also less than thesize of the corresponding portion of the recess l4. The flange l5 includes opposed arcuate portions 5, and the width of the flan e [5 between the sides thereof is less than the width of the recess H, but greater than the width of the slot 3. Also, the maximum extent between the arcuate portions 5 is less than the maximum extent of the circular portion of the recess, but is greater than the extent of the. cutout 4, so that the flange l5 will be held in the recess. The stop pin 25 is adapted to seat in the cutout 4 when the'axle l6 has been rotated to the proper location within the slot 3 to retain the axle therewithin.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

I claim:

1. In a detachable wheel mounting for a boat, a bracket adapted to be connected to the side of the boat, said bracket having laterally spaced apart walls secured to each other along the greater extent of their peripheries and enclosing a vertical recess having one end which opens at the top of said bracket and terminating at its other end in a recess of circular configuration; the outer of said walls having a vertical slot therein which terminates in a cut-out having a horizontally disposed portion; the slot and cutout bearing a superimposed relationship to the vertical and circular recess with the width of the vertical recess being greater than the width of the slot and the maximum extent of the circular recess being greater than the maximum extent of the cut-out, an axle provided with'a flange detachably seated in said slot, said flange having a pair of opposed parallel sides interconnected at each end by arcuate portions with the width of the flange between the sides being less than the width of the recess but greater than the width of the slot and with the maximum extent between the arcuate end portions of the flange being less than the maximum extent of the circular recess but greater than the maximum extent of the cut-out so that when the flangewith its laterally outwardly extending axle is inserted extent of their peripheries and enclosing avertical recess having one end whichopensatthefiOP'jof said bracket and terminating at its other endin a recess of circular configuration; the outer of said walls having a vertical slot therein which terminates in a cut-out having a horizontall; disposed portion; the slot and cut-out bearing a superim posed relationship to the vertical and circular recess with the width of the vertical recess being greater than the width of the slot and-thfe maximum-extent of the circular recess beinggreater than .the maximum extent of the cut-out, an axle provided with a flange detachably seated in said slot, said flange having a pair of opposed parallel sides interconnected at each end by -arcuateiportions With the width of the flange between the sides being less than the Width of the recess .but great'errthan vthe'width :ofv-the slot and 4 with the maximum extent between the arcuate end portions of the flange being less than the maximum extent of the circular recess but greater than the maximum extent of the cut-out so that when the flange with its laterally outwardly extending axle is inserted in the vertical recess, the axle will extend out of the slot and the relative widths of the slot and flange will 7 prevent the flange rmmramng' out, a stop pin mounted on saidaxle and adapted to seat in said cut-out when the axle has been rotated to the proper location within the slot to retain the axle therewith in an-arm having one end secured to said axle for rotating the axle in said slot and a handle secured to the other end of said arm. v I THOMAS A.
